Abstract: PURPOSE: A circuit for generating internal power-supply of a memory device is provided to generate an internal power-supply of a memory device by dropping an external power-supply to a predetermined level. CONSTITUTION: A circuit(200) for generating internal power-supply of a memory device includes a first comparator(220), a switch(210,220), a second comparator(240), a driver(250). The first comparator compares a voltage level of an internal power voltage with a predetermined reference voltage, and generates a predetermined control signal. The switch is activated by the control signal. One end of the switch is connected to an external power-supply voltage. The second comparator is connected to the other end of the switch, compares a voltage level of the internal power-supply voltage with the reference voltage, and generates a predetermined driving signal. The driver responds to the driving signal, and is activated if the internal power-supply voltage is lower than the reference voltage level, and thus raises an internal power-supply voltage level. The switch is activated when the internal power-supply level is lower than the reference voltage, and raises the internal voltage level, and cuts off providing external power-supply voltage to the second comparator.
